Embodiment 1

[0021] Example 1, the composition of this scheme can be divided into: phthalocyanine red 7%, phthalocyanine blue 7%, phthalocyanine green 7%, sunfast scarlet 10%, colorless macromolecule 39%, titanium dioxide 15%, Extender 5%, polyethylene low molecular wax 5%, thermoplastic resin 5%;

[0022] The preparation method is: milling-stirring-granulation-foaming soap;

[0023] The milling process is as follows: phthalocyanine red, phthalocyanine blue, phthalocyanine green, sun-fast scarlet, colorless macromolecule, and titanium dioxide are milled into powder through milling equipment, and the particles are required to be similar. The unqualified material is unqualified and needs to be ground again after grinding;

[0024] The mixing process is as follows: the mixing process is: put the ingredients after grinding into powder according to the ratio and put them into the mixer for mixing, during the mixing period, put the extender and polyethylene low-molecular wax, and the mixer runs...

Embodiment 2

[0031] Example 2, phthalocyanine red 12%, phthalocyanine blue 12%, phthalocyanine green 12%, light fast red 14%, colorless macromolecule 18%, titanium dioxide 16%, extender 5%, polyethylene low molecular weight Wax 5%, and the rest of the ratio is supplemented by dispersant. In the mixing process, phthalocyanine red, phthalocyanine blue, phthalocyanine green, light fast red, colorless macromolecule, titanium dioxide are put in first, and extenders, Polyethylene low-molecular-weight wax, finally drop into dispersant, in stirring process, the input mode of dispersant is to inject 20% of total dispersant dose every five minutes when stirring, finish injecting dispersant by 5 times, this embodiment requires finished product The graininess is obvious, and it is used when the grain hardness is required to be high.

Abstract

The invention belongs to a white polyethylene color master batch with high reflectivity effect, and a preparation method thereof. The white polyethylene color master batch comprises the following components in percentage by weight: 7% of phthalocyanine red, 7% of phthalocyanine blue, 7% of phthalocyanine green, 10% of light fast scarlet, 39% of colorless macromolecules, 15% of titanium dioxide, 5%of an extender, 5% of polyethylene low-molecular wax and 5% of a thermoplastic resin. The preparation method comprises the following steps: grinding, stirring, granulating and soap soaking. Accordingto the invention, the dispersion of different inorganic filling material particles in a resin matrix is improved, the agglomeration between the inorganic filling materials in a resin is avoided, theproduction process of the high-reflectivity white color master batch is optimized, the high reflectivity and the dispersing performance of the processed product of the color master batch are improved,the application field of the terminal finished product is further expanded, the preparation is simple, the cost is reduced and the quality is controllable.

Description

technical field [0001] The invention belongs to the field of polymer material processing, and in particular relates to a white polyethylene color masterbatch with high reflectivity effect and a preparation method thereof. Background technique [0002] A plastic colorant that is well dispersed with a high proportion of pigments or additives and thermoplastic resins. The selected resin has a good wetting and dispersing effect on the colorant, and has good compatibility with the material to be colored. [0003] At present, the white polyethylene masterbatch is mainly filled with titanium dioxide to reflect light, and the reflectivity is limited, generally around 60%, which cannot be widely used. Contents of the invention [0004] In order to achieve the above object, the technical solution adopted in the present invention is that the present invention provides a white polyethylene color masterbatch with high reflectivity effect and its preparation method, and its composition ...
